Girls Trip had me laughing so hard that I could hardly catch my breath.  The last time I laughed like that in a movie theatre was when I watched Bridesmaids.  This movie works for one reason and one reason only...Tiffany Haddish.  If the character of Dina doesn't work, the energy of the entire film would be off and you could create less about the characters..  Thankfully, Haddish's take on Dina is right on time.
